/* This program can be used to convert CPUID Dump from http://instlatx64.atw.hu/

* To build: gcc convert_instlatx64.c -o convert_instlatx64

* To run: ./convert_instlatx64 <input file (from instlatx64)> <output file (without extension)>
|
|
* Then, you can use the create_test.py script to create the test file */
